Description

The present invention relates to an automatic flasher, and more particularly to a failure of the automatic flasher.

Lighting lights installed in facilities such as train stations and on the side of roads use automatic flashers to limit the lighting time zone. The automatic flasher is a switch that switches ON or OFF with a constant illuminance as a threshold value, and does not light during the daytime, but lights up when the surroundings become dark. Further, by incorporating a timer, the light can be turned off at an unnecessary time (such as midnight) (see, for example, Patent Document 1).

When the lighting equipment is not lit, the cause is that the lamp burns out and the automatic flasher fails (including deterioration over time). A worker goes to the site to restore the lighting equipment, measures the circuit voltage using a point-finding device, and identifies the faulty part (see Patent Document 2). If the automatic flasher is out of order, replace it with a new automatic flasher. It is also possible to incorporate a failure detection device into an automatic flasher, detect the failure location from the output voltage and the current flowing between the circuits, and notify the failure location by diode light emission (see Patent Document 3).

At unmanned railway stations, bus stops, and other buildings and facilities, workers are required to perform regular inspections because no one is stationed there. These facilities are scattered over a wide area and are difficult to inspect frequently. Therefore, the non-lighting state due to the failure of the automatic flasher may be left unattended for a long period of time.

In addition, the failure of the automatic flasher may occur not only in a non-lighting state but also in a state in which the light is maintained even during the day (hereinafter referred to as a non-lighting state). In this case, the aging deterioration of the automatic flasher is accelerated, and wasteful power consumption is caused by lighting in an unnecessary time zone.

Therefore, it is required to be able to appropriately deal with the failure of the automatic flasher.

The automatic flasher switching control device according to one aspect of the present invention is applicable to a lighting lamp equipped with an automatic flasher and a lighting device (lighting equipment), and an automatic flasher connected to the lighting device on the secondary side. , Equipped with a switching control unit that can automatically switch between multiple automatic flashers. The switching control unit is in the OFF state when the illuminance or the value corresponding to the illuminance (resistance value, etc.) is equal to or less than a predetermined value for the automatic flasher connected to the lighting equipment on the secondary side (hereinafter, the first failure). It is possible to detect that the illuminance or the value corresponding to the illuminance exceeds a predetermined value and is in the ON state (hereinafter referred to as a second failure).

Then, when the first failure is detected, the switching control unit of the present invention switches from the automatic flasher in which the failure is detected to another automatic flasher. Further, when the second failure is detected, the automatic flasher in which the failure is detected is switched to another automatic flasher. For example, the switching control unit can detect the first failure and the second failure based on the energized state or voltage of the non-grounded side electric wire for output of the automatic flasher, and is capable of detecting the first failure and the second failure, and is a power supply automatic flasher. Can be switched from an automatic flasher in which a failure is detected to another automatic flasher.

For example, in the case of a configuration provided with a timer that limits the operating time of the automatic flasher, the automatic flasher is arranged on the power supply side of the timer so that both the first and second failures can be detected. The output non-grounded side wire can be connected to the timer.

As a configuration for detecting both the first failure and the second failure, the time when the illuminance or the value corresponding to the illuminance is equal to or less than a predetermined value is estimated, and when the automatic flasher does not turn on after that, it is determined as a failure. It is possible to estimate the time when the illuminance or the value corresponding to the illuminance exceeds a predetermined value, and when the illuminance is not turned off after that, it can be determined as a failure. Therefore, the switching control unit can be configured to provide a monitoring timer for setting the time zone for detecting the first and second failures.

For example, the monitoring timer estimates that the first time zone including the estimated lighting time in which the illuminance or the value corresponding to the illuminance is estimated to be equal to or less than the predetermined value, and the illuminance or the value corresponding to the illuminance exceeds the predetermined value. The switching control unit may be operated in the second time zone including the turn-off time, and the start time and stop time of the failure detector may be adjustable according to the sunrise and sunset times.

In order to promptly eliminate the non-lighting state and the non-lighting state in the evening and morning, for example, the monitoring timer sets the switching control unit after the estimated lighting time in which the illuminance or the value corresponding to the illuminance is estimated to be equal to or less than the predetermined value. Is operated, and the switching control unit can be activated after the estimated extinguishing time at which the illuminance or the value corresponding to the illuminance is estimated to exceed a predetermined value.

The automatic flasher switching control method according to another aspect of the present invention is in the OFF state when the illuminance or the value corresponding to the illuminance is equal to or less than a predetermined value with respect to the automatic flasher connected to the lighting fixture on the secondary side. The first failure and the second failure that is in the ON state when the illuminance or the value corresponding to the illuminance exceeds a predetermined value are detected, and when the first failure or the second failure is detected, the lighting fixture Switch the automatic flasher connected to from the automatic flasher for which a failure is detected to another automatic flasher.

According to the present invention, in a lighting facility provided with an automatic flasher, a failure of the automatic flasher can be appropriately dealt with.

An automatic flasher panel 100 and an automatic flasher control panel 200 are installed below the pillar 15, and automatic flashers 50A and 50B are attached to the pillar 15 so as to be exposed. The lighting 10 turns on in the evening when it becomes dim, and turns off in accordance with the end time of use of the station building (midnight, etc.). It turns on again at dawn, when it is still dim, and turns off when it gets bright.

FIG. 2 is a diagram schematically showing an electric circuit (relay circuit) in the automatic flashing instrument panel 100.

The automatic flasher panel 100 is configured with an automatic flasher operation control unit circuit 30 for operating the automatic flashers 50A and 50B. The automatic flasher operation control circuit 30 is provided with a molded case circuit breaker (MCCB) 32A, an electromagnetic contactor (MC) 33, and a molded case circuit breaker 32B. Power is supplied to FIG. 1) through the power supply line L (electric circuit).

Further, power is supplied from the control power supply 39 to the automatic flashers 50A and 50B via the wiring breaker 34 by the power supply line L'. The switching control device 40 provided in the automatic flasher control panel 200 is a device that controls the operation of the automatic flashers 50A and 50B, supplies power to the automatic flashers 50A and 50B, and detects a failure as described later. The automatic flasher 50A and 50B are switched and controlled.

The contact 37A of the timer 37 is connected to the contact 35 (R) of the magnetic contactor 33 via the switch circuit 36, and the power supply line on the ground side is connected to the contact 35 (S) of the magnetic contactor 33. The lamp 20 lights up while the automatic flasher 50A is in the ON state and the timer 37 is operating (starting).

FIG. 3 is a schematic block diagram of the switching control device 40 of the automatic flasher.

The switching control device 40 connects the monitoring timers 41 and 42 for setting the time for monitoring the operating states of the automatic flashers 50A and 50B, and the automatic flasher connected to the power supply line between the power supply and the load (lamp 20). A control unit 44 for switching between the automatic flashers 50A and 50B is provided, and power is supplied to one of the automatic flashers 50A and 50B via a molded case circuit (MCB) 43.

The automatic flasher switching control device 40 is provided with terminal blocks 45A and 45B, and a connection line (power supply line) 60 connected to the automatic flasher 50A and 50B is connected. The power supply lines 60A and 60B of the connection line 60 shown in FIG. 3 are power supply lines connected to the input side terminals of the automatic flasher 50A, and are composed of a non-grounded side power supply line and a grounded side power supply line, respectively. The power supply line 60C is connected to the output side terminal of the automatic flasher 50A, and power is output as a non-grounded side power supply line when the automatic flasher 50A operates. The same configuration applies to the automatic flasher 50B.

Inside the automatic flashers 50A and 50B, Cds circuits 53A and 53B that detect the brightness and switch ON / OFF of the contacts 54A and 54B are provided. When the Cds circuits 53A and 53B detect the illuminance below the predetermined value (threshold value), the contacts 54A and 54B are switched ON, and when the illuminance exceeds the predetermined value, the contacts 54A and 54B are switched OFF. It should be noted that it may be configured to switch ON / OFF based on the resistance value of bimetal or the like.

The control unit 44 detects the open / closed state of the contact 54A by detecting the energized state or the voltage of the power supply line 60C on the non-grounded side with the automatic flasher 50A. When it is detected that the automatic flasher 50A is out of order from the open / closed state of the contact 54A, power is supplied to the automatic flasher 50B and the connection with the power line L is switched. Further, when the automatic flasher 50A fails, the control unit 44 displays a warning to a warning display unit (not shown). Further, the switching of the automatic flasher 50A can be reset by a reset switch (not shown).

FIG. 4 is a diagram showing the connection relationship between the automatic flasher 50A (or the automatic flasher 50B) and the timer 37.

The primary side of the automatic flasher 50A is connected to the power supply, and the secondary side is connected to the timer 37. In the operating time zone of the automatic flasher 50A set by the timer 37, the automatic flasher 50A can be switched ON / OFF according to the ambient illuminance (darkness). As described above, the lamp 20 is automatically turned on when the contact 54A is turned on, and the lamp 20 is automatically turned off when the contact 54A is turned off.

Failure of the automatic flasher 50A occurs with respect to both the ON / OFF state of the contact 54A. That is, there are a state in which the contact 54A must be closed when the illuminance is below a certain level and the contact point 54A is open even though the contact point 54A must be closed, and a state in which the contact point 54A must be opened when the illuminance exceeds a certain level. The automatic flasher switching control device 40 detects the energized state or voltage of the monitoring timers 41 and 42 and the non-grounded side power supply line 60C, and detects two failure patterns, respectively.

The automatic flasher switching control device 40 can be configured by a known mechanical relay including an electromagnetic relay, a reed relay, etc., for example, by a mechanical relay represented by the relay sequence diagram shown in FIG. 7. Can be configured. Further, switching control may be performed by a control unit provided with an arithmetic processing unit such as a CPU.

FIG. 5 is a diagram showing a flow of switching control of the automatic flasher. FIG. 6 is a diagram showing a time chart of switching control of the automatic flasher. Hereinafter, the operation of the switching control device 40 of the automatic flasher will be described.

The automatic flasher 50A is constantly supplied with power, but the timer 37 limits the power supply to the lamp 20, that is, the lighting is restricted. Here, the time zones from 15:00 to 24:00 and 4:30 to 7:00 are set as the time zones for starting the timer 37. At 15:00 (or 4:30), the timer 37 starts (S101), and the state where it can be turned on / off based on the brightness detection of the automatic flasher 50A is until 24:00 (or 7:00). It can be continued (S102).

The monitoring timer 41 operates the control unit 44 during a time zone during which a non-lighting state (first failure) can be detected, and the switching control unit 44 starts and stops according to a time zone set by the monitoring timer 41. Here, it operates in the time zone from 18:00 to 24:00 (S103). On the other hand, the monitoring timer 42 can set a time zone in which a non-lighting state (second failure) can be detected, and here, a time zone from 6:30 to 8:00 is set. The operating time zones of the monitoring timers 41 and 42 may be determined in consideration of the sunset and sunrise times of the year, or the operating time zones may be adjusted according to the season.

When the automatic flasher 50A operates normally, when the brightness becomes equal to or less than a predetermined brightness, the automatic flasher 50A is turned on by switching the switch. In FIG. 6A, the lighting is switched to at 16:00. When the timer 37 stops operating at time 24:00, it goes out at time 24:00. When the timer 37 starts again at 4:30, the switch of the automatic flasher 50A is switched and turned off by detecting that the automatic flasher 50A exceeds a predetermined brightness. In FIG. 6A, the light is turned off at 6:00.

While the monitoring timer 41 is operating, the control unit 44 detects the ON / OFF state of the automatic flasher 50A. If the automatic flasher 50A is in the OFF state during the operation time of the monitoring timer 41, it is determined that the automatic flasher 50A is not lit (S104), and the power is switched to the automatic flasher 50B to switch the automatic flasher 50B to the timer 37. Connect. At the same time, the warning display unit notifies the failure (S105, S106).

FIG. 6B shows that the non-lighting state was detected immediately after the monitoring timer 41 was started (18:00), and the light was turned on by switching to the automatic flasher 50B. As long as the non-lighting state is not detected, the lighting and extinguishing are switched in the time zone set by the timer 37 (S107).

While the monitoring timer 42 is operating, the control unit 44 detects the ON / OFF state of the automatic flasher 50A (S108). When the automatic flasher 50A is in the ON state during the operating time of the monitoring timer 42, it is determined that the light is not turned off (S109), a failure notification is displayed, and the power is supplied from the automatic flasher 50A to the automatic flasher 50B. The supply is switched and connected to the power supply line L (S105, S106). FIG. 6C shows that the non-lighting state was detected immediately after the monitoring timer 42 was started (6:30), and the light was turned off by switching to the automatic flasher 50B. Unless a non-lighting state is detected, the automatic flasher 50A operates normally.

As described above, according to the present embodiment, in the lighting 10 that automatically turns on and off using the automatic blinker, the switching control device 40 that can switch the automatic blinker to be used between the automatic blinkers 50A and 50B. It is equipped with. The switching control device 40 includes monitoring timers 41 and 42, and a control unit 44, and is set by the monitoring timer 42 when the automatic flasher 50A is in the OFF state during the evening to midnight time zone set by the monitoring timer 41. When the automatic flasher 50A is in the ON state in the morning time zone, the control unit 44 switches from the automatic flasher 50A to the automatic flasher 50B. It should be noted that it may be configured to switch between three or more automatic flashers.

By preparing two automatic flashers 50A and 50B in advance, it is possible to maintain appropriate lighting even if a failure occurs in the lighting equipment arranged in an unmanned station or the like. Further, by detecting not only the non-lighting state but also the non-lighting state, it is possible to suppress deterioration over time and reduce power consumption. Further, the automatic flasher 50A is arranged on the power supply side of the timer 37, and the automatic flasher 50A is constantly supplied with power while the lighting is restricted by the timer 37. Since the power ON / OFF of the automatic flasher 50A is not forcibly switched due to the influence of the timer 37, it is possible to detect both the non-lighting state and the non-lighting state while suppressing the risk of failure of the automatic flasher 50A. can. The timer 37 may be configured to be arranged on the power supply side of the automatic flasher 50A. In this case, the monitoring time zone of the monitoring timers 41 and 42 may be set according to the operating time zone of the lamp 20 (load), that is, according to the operating time zone of the timer 37.

Furthermore, by setting the monitoring time with the monitoring timers 41 and 42, the difference between the ON / OFF state (in the normal case) of the automatic flasher estimated near the sunset and sunrise times and the detected ON / OFF state. Therefore, it is possible to detect a non-lighting state and a non-lighting state.

As for the lighting, it is possible to configure not only a single-pillar type lighting but also a utility pole-mounted type lighting, and it is also possible to install it on a highway or a general road. Furthermore, it can be applied to lighting devices and lighting equipment installed in waiting rooms of station buildings and bus stops.
